Here is my problem: I export a database A_DB using "export" function of Phppgadmin. The dump file A_dump.sql includes both the database structure and data. Then I try to create another blank database B_DB, and import A_dump.sql into it.

Every time I do that, the transaction failed with no error reported:

SQL error:
In statement:

Is there some logs that I can find in phppgadmin that would allow me to investigate this problem? I have tried searching for an hour, but still not find anything.
